Conducting Elgar's Wand of Youth suites : programming possibilities and perspectives on performance
… Edward Elgar’s suites op. 1a and 1b, titled The Wand of Youth: Music to a Child’s Play. Sources for this work draw from the extensive scholarly writings on Elgar’s biography, compositional practice, and recordings, as well as from sources discussing issues of conducting analysis, gesture, and …

The flick of the wrist and the wave of the wand: low-level mechanisms for inducing change blindness
This dissertation explores a new paradigm for inducing change blindness as an avenue for understanding the stimulus conditions that give rise to change blindness in general. Participants are asked to detect an instantaneous change in orientation of a single item in an array of Gabor patches. While …

New approaches to higher-dimensional general relativity
… is such a multiple Weyl aligned null direction (WAND) if and only if it is tangent to a shearfree null geodesic congruence. This is not the case in higher dimensions. However, I have formulated and proved a partial generalization of the result to arbitrary dimension, namely that a spacetime …

The challenges faced by the only black team playing 6-down touch rugby at In2Touch : "I just saw all these white people and just thought Wah...what is going to happeb to us!"
… not available for all. Sport itself is not magic-wand through which people naturally find it possible to put behind them societal differences. Differences from greater society are mirrored in sport and this was evident from my data.

Usability Studies with Virtual and Traditional Computer Aided Design Environments
… of the user's head position and position of a wand in 3D space. It is argued that with these immersive technologies along the use of gestures and hand movements should provide a more natural interface with the immersive virtual environment. This allows a more rapid and efficient set of actions …

Usability of immersive virtual reality input devices
… a commercially available Intersense<sup> ©</sup> Wand and a home built pinch glove and wireless receiver. Users were asked to carry out a series of minor tasks involving placement of shaped blocks into corresponding holes within an Immersive Virtual Reality Environment. Performance was evaluated …

The law of retrenchment: s 189a facilitation - the impact of facilitation in large-scale retrenchments
… facing tough business challenges often wave the wand of retrenchment in the hope that the problem will go away. This often leads to workers unexpectedly finding themselves unemployed and queuing at the unemployment offices. In 2002, legislative provisions were introduced into the statute dealing …

Kontrolle freier Ränder bei der Erstarrung von Kristallschmelzen
… Als Kontrollgrößen dient die Temperatur auf der Wand des Schmelztiegels und/oder wandnahe oder verteilte Lorentzkräfte. Das Kontrollziel wird durch Minimierung eines geeigneten Kosten-Funktionals erreicht. Das daraus resultierende Minimierungsproblem wird mit einem Adjungierten-Ansatz gelöst. …

Robotic ultrasound manipulator : calibration of position and orientation measurement system
… for holding and manipulating an ultrasound wand as adeptly as a trained technician. From the 2D slices recorded by an ultrasound transducer, a three-dimensional image can be reconstructed. To reconstruct the 3D image, position and orientation data are needed. In the interests of space and …
